Ports of Auckland has lost its contract with the country's largest exporter, Fonterra.
The move will see weekly trade worth around $27 million re-routed through the ports of Tauranga and Napier.
Ports of Auckland Chief Executive Tony Gibson says the threat of ongoing industrial action means it's inevitable customers will look for alternatives and contingencies.
Tony Gibson says he's today advised the union that the port's latest - and ninth - offer is its best and final one.
The next strike action is planned for a 48 hour period from Monday morning.
We wonder what the Maritime Union's response is going to be when the job losses start; after all, Ports of Auckland Limited have now lost a huge chunk of revenue due to Maersk and Fonterra voting with their feet to ensure the continuity of service.
And shouldn't the first duty of a trade union be to protect the jobs of its members, rather than expose the member to the possibility of unemployment?
